目的 总结和分析全国感染监控网医院感染发病率及病原菌分布。方法 对监控网医院１９９８年６月～１９９９年５月逐月上报资料进行统计分析。结果 １年共监测患者１２５３６７１人，发生医院感染４９１０９人共５１８２０例次，医院感染发病率为３．９２％，医院感染例次感染率４．１３％；感染部位以下呼吸道感染最多见，次为胃肠道、术后伤口、泌尿道感染；共分离病原体１２２６５株，以大肠埃希菌、铜绿单胞菌、金黄色葡萄球菌、表皮葡萄球菌、肠杆菌属细菌、白色念珠菌、克雷伯菌属细菌多见。结论 监控网医院感染发病率为３．９２％，以下呼吸道感染最常见，病原菌以大肠埃希菌、铜绿假单胞菌、金黄色葡萄球菌多见。

Analysis of the Data from National Nosocomial Infection Surveillance System between 1998 and 1999

OBJECTIVE To investigate the nosocomial infection incidence of National Surveillance System and distribution of the pathogens. METHODS Summaries and analysis of the data of surveillance system hospitals from June, 1998 to May 1999 were provided. RESULTS Total of 1253671 patients were under surveillance, 51820 nosocomial infection cases were occurred among 49109 patients, the nosocomial infection incidence was 3.29%, and the case infection incidence was 4.13%; lower respiratory tract infection was the most frequent infection site, followed by gastroenteric tract infection, postoperatve incisional infection and urinary tract infection. 12265 Strains of pathogens were isolated, the most common pathogens were Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Enterobacter, Candida albicans, Klebsiella. CONCLUSIONS The hospital infection rate of surveillance system was 3.92%, lower respiratory tract infection ranked the first, the most common pathogens were E.coli, P.aeruginosa, S.aureus.
